Recoverable graphene-Rh organometallic catalyst as an active catalyst for promoting organic

In this work, a new catalyst, Graphene−magnetic Rhodium nanohybrid was synthesized and characterized. The Rh(I) organometallic magnetic nanoparticles form a novel class of heterogeneous catalyst which are particularly suitable for the practice of organic synthesis in an environmentally friendly manner. High yield, low reaction times, the use of green solvents and non-toxicity of the catalyst are the main merits of this protocol. Also Magnetic separation is an environmentally-friendly alternative for the separation and recovery of catalysts, since it minimizes the use of solvents and auxiliary materials, reduces operation time, minimizes catalyst loss by preventing mass loss and oxidation, and energy. This magnetic catalyst showed high catalytic activity towards the Suzuki–Miyaura reaction in the ethanol– water solution
